Deputy Premier Bryan Green and Federal Environment Minister Tony Burke will facilitate Friday's meeting described as the ``last hurrah'' for the two-year process attempting to end the 30-year conflict.

Groups requested government involvement after failing to reach agreement on their own. However, they will still meet every day to discuss the issues before Friday.

The groups were close to reaching agreement a fortnight ago but further modelling showed the reserve scenario would not produce enough wood supply to satisfy the industry's demands.

Mr Green said yesterday the dramatic write-down of Gunns assets was proof that the state Opposition's ``do nothing'' approach on forestry would not work.

``Mr Hodgman is trying to con people into believing that everything will be fine if we abandon the Tasmaniana Forest Agreement but it remains the only possible solution on the table,'' Mr Green said.

Greens Leader Nick McKim had still not made up his mind yesterday whether to seek a place in the negotiating room on Friday.
